BTW - just talking to [Internet Gure Omega (not real name)] and he rang
someone in ITS to ask re hop maximums. Apparently it started out as 16 in
the early days, then went to 30, and now can be more than this due to
smart routers or something.
Re our large number of hops, he drew me a diagram of a "router hotel" which
he said is common. Link comes in from (eg) .au then goes to another router
because this 1st one only handles traffic direct to (eg) .ca, .fr, .za -
this 2nd router similarly doesn't do .uk directly so again it gets passed
onto another one, etc. Basically a case of what happens when you have to
process 200 domains with only 10 or 15 routers in the rack.
Cheers,
Tony
